Intelligent warning system

ABSTRACT

Various embodiments described herein relate to an intelligent warning system in a communication service. One embodiment of the present invention analyzes a user&#39;s biometric signals and image data of one of the user&#39;s in a communication session to determine a distress level. In addition, location data indicating the user&#39;s velocity and direction can be used to determine a distress level. If the biometric signals or the image data indicate a distress level that meets or exceeds a threshold level, a notification is automatically sent to a remote user. This can allow a remote user to render assistance to a user in distress, even when the user is unable to communicate one or more conditions.

BACKGROUND

Modern electronic devices come with a plethora of sensors and can do amazing things, yet sometimes they cannot do the most useful and most important tasks. In some instances, during a communication session, for example, it is vital to communicate the user's condition. When users are faced with a possible sudden life-threatening condition, they may be unable to convey that condition to the other user(s), and as such, the other user would be none the wiser to appreciate the severity of the situation.

For example, the user may be experiencing shortness of breath, a heart attack, or stroke, thereby making it difficult, or render the user incapable to speak or deliver a message to the other user of the present condition and urgent need for immediate medical assistance. In other instances, the user may be unaware of his/her present condition, as the onset of a life-threatening condition may be sudden, and the user would not have time to deliver a message to the other user in a chatting session.

Despite having a fully capable device that could monitor the user's pulse, and “see” the user through cameras and environmental awareness, a user may have a dire medical condition yet the device would not know and would take no action to help keep the person safe and/or notify the other user in the chat session so they could intervene. Therefore, there is a need for improved communication systems to address these issues. It is with respect to these and other considerations that the disclosure made herein is presented.

SUMMARY

The present invention provides a method for using a biometric signal in a communication system to generate intelligent warning signals. In some embodiments, one or more streams associated with a communication session comprise biometric data of a user participating in the communication session. For example, a server may be in communication with a network, such as the Internet or cellular network, where it can receive the data from an end-user device, such as a phone or a tablet. The techniques disclosed herein provide a system for analyzing at least one aspect of the biometric data. For example, the server might have access to a biometric detection module, which can analyze the biometric signals and determine a user condition or state.

The system can then determine if an aspect of the biometric data meets one or more criteria. For example, the server might access a biometric data table in memory that lists various characteristics of the biometric signal and associates those characteristics with a known user condition or state. One biometric signal might be the user's pulse and a particular reading might indicate a characteristic of the pulse, such as “the pulse is high” or the “pulse is low.” In such cases, the server determines that criteria associated with the user's pulse has been met. Once the criteria has been met, a notification may be generated. The notification can be a graphical display, an audio signal or any other indicator, such as a light or tactile interface. In another example, if a user moves in a particular pattern, velocity, or direction that indicates distress, the server may determine that criteria associated with the user has been met. Thus, if a user is moving in a particular direction or velocity that is outside a defined threshold, a notification may be generated.

In response to determining that one or more criteria has been met, the techniques disclosed herein provide a system that can display a notification on a graphical user interface or generate an audio signal to indicate a condition of a user. In some configurations, a computer may display a rendering of information associated with the biometric data. For example, if the user's pulse rate fell into a range associated with the characteristic of meeting the criteria, e.g., critically close to death, the server would cause to use data from the biometric data table which alerts the other users with the specified notification regarding the user's condition. If the user was found to be moving in a pattern that indicated distress, one or more warnings would be generated for remote users.

In some configurations, the biometric data, the location data indicating movement, and other information associated with the user can be used to generate one or more values indicating a distress level. For instance, the biometric data at a particular heart rate and temperature may cause the generation of the first score, movement patterns from the location data may cause the generation of a second score, and image data from a camera detecting facial expressions or bodily movement can cause the generation of a third score. The scores can be combined or otherwise processed using one or more algorithms to determine an accumulative score which can be compared against the threshold. The notifications described herein can be triggered when the accumulative score meets or exceeds the threshold. It can be appreciated that any of these scores can be used individually or in any combination to determine an accumulative score. Thus, any of the sensors described herein can be used individually or in any combination to generate the notifications described herein.

DETAILED DESCRIPTION

The present invention enables a user's device, such as a cellular phone or smartwatch, to alert another user when the user's physical condition meets a threshold. Computing systems enabled with sensors, capable of measuring at least a pulse and/or movement of a user, and/or equipped with a camera allow for enhanced analysis of the user's physical characteristics to determine a level of distress. In response to determining that the level of distress, a score of which may be compared against a threshold of one or more criteria, one or more notifications may be generated and communicated to remote users. The notifications may simply provide notice of a particular condition or level of distress, or the notifications may provide more detailed descriptions of the user's physical condition or a level of distress.

In one example, the computing device might be a smartphone with a front-facing camera or a wearable device such as a smart-watch. If a user were in a communication session with another user's computing device and began walking or jogging, the system could monitor the velocity of the user, determine the heart rate and in conjunction analyze the user's facial characteristics to determine if delivering an S.O.S. notification would be necessary. In another example, the user might experience a sudden onset of a heart attack or other ailment. The user's pulse rate might dip or spike abnormally low or high. The user may also manifest severe physical expressions of discomfort and distress. Then, the system would analyze these physical characteristics along with a determination of whether the biometric data meets the threshold and warrant an S.O.S. alert to the other computing device.

The present invention is an intelligent warning system as shown in FIG. 1, which includes a communication session 104 between a number of client computing devices 106(1) through 106(N) (where N is a positive integer number having a value of two or greater). The client computing devices 106(1) through 106(N) enable users to participate in the communication session 104.

In this example, the communication session 104 may be hosted, over one or more network(s) 108, by the system 102. That is, the system 102 may provide a service that enables users of the client computing devices 106(1) through 106(N) to participate in the communication session 104. As an alternative, the communication session 104 may be hosted by one of the client computing devices 106(1) through 106(N) utilizing peer-to-peer technologies.

The system 102 includes device(s) 110, and the device(s) 110 and/or other components of the system 102 may include distributed computing resources that communicate with one another, with the system 102, and/or with the client computing devices 106(1) through 106(N) via the one or more network(s) 108. In some examples, the system 102 may be an independent system that is tasked with managing aspects of one or more communication sessions 104.

Network(s) 108 may include, for example, public networks such as the Internet, private networks such as an institutional and/or personal intranet, or some combination of private and public networks. Network(s) 108 may also include any type of wired and/or wireless network, including but not limited to local area networks (“LANs”), wide area networks (“WANs”), satellite networks, cable networks, Wi-Fi networks, WiMax networks, mobile communications networks (e.g., 3G, 4G, and so forth) or any combination thereof. Network(s) 108 may utilize communications protocols, including packet-based and/or datagram-based protocols such as Internet protocol (“IP”), transmission control protocol (“TCP”), user datagram protocol (“UDP”), or other types of protocols. Moreover, network(s) 108 may also include a number of devices that facilitate network communications and/or form a hardware basis for the networks, such as switches, routers, gateways, access points, firewalls, base stations, repeaters, backbone devices, and the like.

In some examples, network(s) 108 may further include devices that enable connection to a wireless network, such as a wireless access point (“WAP”). Example networks support connectivity through WAPs that send and receive data over various electromagnetic frequencies (e.g., radio frequencies), including WAPs that support Institute of Electrical and Electronics Engineers (“IEEE”) 802.11 standards (e.g., 802.11g, 802.11n, and so forth), and other standards.

In various examples, device(s) 110 may include one or more computing devices that operate in a cluster or other grouped configuration to share resources, balance load, increase performance, provide fail-over support or redundancy, or for other purposes. For instance, device(s) 110 may belong to a variety of classes of devices such as traditional server-type devices, desktop computer-type devices, and/or mobile-type devices. Thus, although illustrated as a single type of device—a server-type device—device(s) 110 may include a diverse variety of device types and are not limited to a particular type of device. Device(s) 110 may represent, but are not limited to, server computers, desktop computers, web-server computers, personal computers, mobile computers, laptop computers, mobile phones, tablet computers, or any other sort of computing device.

A client computing device (e.g., one of client computing device(s) 106(1) through 106(N)) may belong to a variety of classes of devices, which may be the same as, or different from, device(s) 110, such as traditional client-type devices, desktop computer-type devices, mobile-type devices, special purpose-type devices, embedded-type devices, and/or wearable-type devices. Thus, a client computing device can include, but is not limited to, a desktop computer, a game console and/or a gaming device, a tablet computer, a personal data assistant (“PDA”), a mobile phone/tablet hybrid, a laptop computer, a communication device, a computer navigation type client computing device such as a satellite-based navigation system including a global positioning system (“GPS”) device, a wearable device, a virtual reality (“VR”) device, an augmented reality (AR) device, an implanted computing device, an automotive computer, a network-enabled television, a thin client, a terminal, an Internet of Things (“IoT”) device, a work station, a media player, a personal video recorder (“PVR”), a set-top box, a camera, an integrated component (e.g., a peripheral device) for inclusion in a computing device, an appliance, or any other sort of computing device. In some implementations, a client computing device includes input/output (“I/O”) interfaces that enable communications with input/output devices such as user input devices including peripheral input devices (e.g., a game controller, a keyboard, a mouse, a pen, a voice input device, a touch input device, a gestural input device, and the like) and/or output devices including peripheral output devices (e.g., a display, a printer, audio speakers, a haptic output device, and the like).

Client computing device(s) 106(1) through 106(N) of the various classes and device types can represent any type of computing device having one or more processing unit(s) 112 operably connected to computer-readable media 114 such as via a bus 116, which in some instances can include one or more of a system bus, a data bus, an address bus, a PCI bus, a Mini-PCI bus, and any variety of local, peripheral, and/or independent buses. The computer-readable media 114 may store executable instructions and data used by programmed functions during operation. Examples of functions implemented by executable instructions stored on the computer-readable media 114 may include, for example, an operating system 128, a client module 130, other modules 132, and programs or applications that are loadable and executable by processing unit(s) 112.

Client computing device(s) 106(1) through 106(N) may also include one or more interface(s) 134 to enable communications with other input devices 148 such as network interfaces, cameras, keyboards, touch screens, and pointing devices (mouse). For example, the interface(s) 134 enable communications between client computing device(s) 106(1) through 106(N) and other networked devices, such as device(s) 110 and/or devices of the system 102, over network(s) 108. Such network interface(s) 134 may include one or more network interface controllers (NICs) or other types of transceiver devices to send and receive communications and/or data over a network.

In the example environment 100 of FIG. 1, client computing devices 106(1) through 106(N) may use their respective client modules 130 to connect with one another and/or other external device(s) in order to participate in the communication session 104. For instance, a first user may utilize a client computing device 106(1) to communicate with a second user of another client computing device 106(2). When executing client modules 130, the users may share data, which may cause the client computing device 106(1) to connect to the system 102 with the other client computing devices 106(2) through 106(N) over the network(s) 108.

The client module 130 of each client computing device 106(1) through 106(N) may include logic that detects user input and communicates control signals to the server relating to controlling aspects of the communication session 104. For example, the client module 130 in the first client computing device 106(1) in FIG. 1 may detect a user input at an input device 148. The user input may be sensed, for example, as a finger press on a user interface element displayed on a touchscreen, or as a click of a mouse on a user interface element selected by a pointer on the display 150. The client module 130 translates the user input according to a function associated with the selected user interface element.

As discussed above, one or more streams from client computing devices 106 in environment 100 comprise image data 199 of a user participating in the communication session 104. The client module 130 may send a control signal 156(1) (also referred to herein as a “control command” or an “indication”) to a server (for example, a server operating on the device 110) to perform the desired function.

In one embodiment, the system 102 may receive one or more streams associated with a communication session 104, the one or more streams comprising image data 199 of a user participating in the communication session 104. The system 102 may analyze the image data by examining at least one physical feature of the user using an emotion detection module 198 to determine an emotion signal. If an emotion is detected, it selects the emotion signal from a list of emotions in an emotion data table 135.

For example, a first user in a communication session 104 may be experiencing sudden, sharp pains in her body. At this time, her expression may change from a neutral one to a grimacing, stressed expression. The user's change in expression would be captured and analyzed by the system 102. Next, the user's grimace of pain and stress would be determined to be a change of emotion, and thereby generate an emotion signal. The system 102 would select from a list of emotions in the emotion data table 135.

The system 102 may also use a location module 177. The location module 177 determines the location of the user by receiving location data 111, for example from the GPS sensors of a cellular phone, which are components of one of the client devices 106(1-N), the location module 177 can also track whether the user changes direction by keeping track of the user's motion and location and how many times they change direction. The location module 177 can store this information in a location data table 129. For example, in a health emergency the user could continually move back and forth, which the system 102 detects and can record as a factor in whether the user is physically distressed. The location module 177 tracks the user's movements throughout this time to understand their behavior.

The system 102 also employs a biometric detection module 188 in order to determine a biometric signal. While the user is experiencing sudden and sharp pains through her body, her pulse rate may elevate at a rapid rate. The biometric detection module 188 detects the elevated pulse rate and keeps track of the pulse values.

The system 102 also includes a threshold determination module 166 (TDM 166). The TDM 166 accesses the data store 138 to retrieve values from the location data table 129, the biometric data table 217, and the emotion data table 135 and applies these values to a formula to determine if a threshold has been met or exceeded. If the threshold is exceeded the TDM 166 sends a signal to the notification module 133.

At the instance the TDM 166 has informed the notification module 133, it sends a notification 218 to the other user's client computing devices 106 (1-N) participating in the communication session 104. In this example, the TDM 166 has received all three signals from the user while she has experienced these sudden and sharp pains throughout her body and if it is determined that the user has met the threshold, the system would send a notification 218 to the other users participating in the communication session that the user was in distress, in need of assistance, and would share the user's location.

As shown in FIG. 1, the device(s) 110 of the system 102 includes a server module 136, a data store 138, and an output module 140. The server module 136 is configured to receive, from individual client computing devices 106(1) through 106(N), streams 142(1) through 142(M) (where M is a positive integer number equal to 2 or greater). In some scenarios, not all the client computing devices utilized to participate in the communication session 104 provide an instance of streams 142, and thus, M (the number of instances submitted) may not be equal to N (the number of client computing devices). In some other scenarios, one or more of the client computing devices 106 may be communicating an additional stream 142 that includes content, such as a document or other similar type of media intended to be shared during the communication session 104.

The server module 136 is also configured to receive, generate and communicate session data 144 and to store the session data 144 in the data store 138. The session data 144 can define aspects of a communication session 104, such as the identities of the participants, the content that is shared, etc. In various examples, the server module 136 may select aspects of the streams 142 that are to be shared with the client computing devices 106(1) through 106(N). The server module 136 may combine the streams 142 to generate communication data 146 defining aspects of the communication session 104. The communication data 146 can comprise individual streams containing select streams 142. The communication data 146 can define aspects of the communication session 104, such as a user interface arrangement of the user interfaces on the client computing devices 106, the type of data that is displayed and other functions of the server module 136 and client computing devices. The server module 136 may configure the communication data 146 for the individual client computing devices 106(1)-106(N). Communication data can be divided into individual instances referenced as 146(1)-146(N). The output module 140 may communicate the communication data instances 146(1)-146(N) to the client computing devices 106(1) through 106(N). Specifically, in this example, the output module 140 communicates communication data instance 146(1) to client computing device 106(1), communication data instance 146(2) to client computing device 106(2), communication data instance 146(3) to client computing device 106(3), and communication data instance 146(N) to client computing device 106(N), respectively.

The communication data instances 146(1)-146(N) may communicate audio that may include video representative of the contribution of each participant in the communication session 104. Each communication data instance 146(1)-146(N) may also be configured in a manner that is unique to the needs of each participant user of the client computing devices 106(1) through 106(N). Each client computing device 106(1) through 106(N) may be associated with a communication session view. Examples of the use of communication session views to control the views for each user at the client computing devices 106 are described with reference to FIG. 2.

FIG. 2 is a block diagram of an example device in the communication system of FIG. 1. The device 200 may represent one of device(s) 110 where the device 200 includes one or more processing unit(s) 202, computer-readable media 204, and communication interface(s) 206. The components of the device 200 are operatively connected, for example, via a bus 207, which may include one or more of a system bus, a data bus, an address bus, a PCI bus, a Mini-PCI bus, and any variety of local, peripheral, and/or independent buses.

As utilized herein, processing unit(s), such as the processing unit(s) 202 and/or processing unit(s) 112, may represent, for example, a CPU-type processing unit, a GPU-type processing unit, a field-programmable gate array (“FPGA”), another class of digital signal processor (“DSP”), or other hardware logic components that may, in some instances, be driven by a CPU. For example, and without limitation, illustrative types of hardware logic components that may be utilized include Application-Specific Integrated Circuits (“ASICs”), Application-Specific Standard Products (“ASSPs”), System-on-a-Chip Systems (“SOCs”), Complex Programmable Logic Devices (“CPLDs”), etc.

As utilized herein, computer-readable media, such as computer-readable media 204 and/or computer-readable media 114, may store instructions executable by the processing unit(s). The computer-readable media may also store instructions executable by external processing units such as by an external CPU, an external GPU, and/or executable by an external accelerator, such as an FPGA type accelerator, a DSP type accelerator, or any other internal or external accelerator. In various examples, at least one CPU, GPU, and/or accelerator is incorporated in a computing device, while in some examples one or more of a CPU, GPU, and/or accelerator is external to a computing device.

Computer-readable media may include computer storage media and/or communication media. Computer storage media may include one or more of volatile memory, nonvolatile memory, and/or other persistent and/or auxiliary computer storage media, removable and non-removable computer storage media implemented in any method or technology for storage of information such as computer-readable instructions, data structures, program modules, or other data. Thus, computer storage media includes tangible and/or physical forms of media included in a device and/or hardware component that is part of a device or external to a device, including but not limited to random-access memory (“RAM”), static random-access memory (“SRAM”), dynamic random-access memory (“DRAM”), phase change memory (“PCM”), read-only memory (“ROM”), erasable programmable read-only memory (“EPROM”), electrically erasable programmable read-only memory (“EEPROM”), flash memory, compact disc read-only memory (“CD-ROM”), digital versatile disks (“DVDs”), optical cards or other optical storage media, magnetic cassettes, magnetic tape, magnetic disk storage, magnetic cards or other magnetic storage devices or media, solid-state memory devices, storage arrays, network attached storage, storage area networks, hosted computer storage or any other storage memory, storage device, and/or storage medium that can be used to store and maintain information for access by a computing device.

In contrast to computer storage media, communication media may embody computer-readable instructions, data structures, program modules, or other data in a modulated data signal, such as a carrier wave, or other transmission mechanism. As defined herein, computer storage media does not include communications media. That is, computer storage media does not include communications media consisting solely of a modulated data signal, a carrier wave, or a propagated signal, per se.

Communication interface(s) 206 may represent, for example, network interface controllers (“NICs”) or other types of transceiver devices to send and receive communications over a network. The communication interfaces 206 are used to facilitate communication over a data network with client computing devices 106.

In the illustrated example, computer-readable media 204 includes the data store 138. In some examples, the data store 138 includes data storage such as a database, data warehouse, or other type of structured or unstructured data storage. In some examples, the data store 138 includes a corpus and/or a relational database with one or more tables, indices, stored procedures, and so forth to enable data access including one or more of hypertext markup language (“HTML”) tables, resource description framework (“RDF”) tables, web ontology language (“OWL”) tables, and/or extensible markup language (“XML”) tables, for example.

The data store 138 may store data for the operations of processes, applications, components, and/or modules stored in computer-readable media 204 and/or executed by processing unit(s) 202 and/or accelerator(s). For instance, in some examples, the data store 138 may store session data 208 (e.g., session data 144), profile data, and/or other data. The session data 208 may include a total number of participants in the communication session 104, and activity that occurs in the communication session 104 (e.g., behavior, activity of the participants), and/or other data related to when and how the communication session 104 is conducted or hosted. Examples of profile data include, but are not limited to, a participant identity (“ID”) and other data.

In an example implementation, the data store 138 stores biometric data 160, image data 199, location data 111 that is received by one or more biometric sensors. The system 102 generates communication data 146 that when displayed by the display of client computing device 106(2), allows the client computing device 106(2) to display any one of the notifications 218 that are associated with the biometric data 160 of the first user, where the biometric data 160 is analyzed from the first user that is in communication with the client computing device 106(1), thereby displaying the notification 218 on the client computing device 106(2) of the second user.

In another example, if the first user's biometric data 160 has a signature that the biometric detection module 188 matches to a physical state of the first user, the view of the second user's display would be changed. For example, if the first and second users are in a communication session 104 and the first user's pulse rate reached a certain value to indicate a high pulse, the notification module 133 selects a notification 218 from a biometric data table 217 that is associated with the physical state of having a high pulse. This causes a display of a notification 218 associated with the first user's biometric data 160 and sends it to the second user's client computing device 106(1-N). As noted above, the data store 138 may store the streams 142, communication session views 250, session data 208, image data 199, biometric data 160 and a biometric data table 217.

Alternately, some or all of the above-referenced data can be stored on separate memories 224 on board one or more processing unit(s) 202 such as a memory on board a CPU-type processor, a GPU-type processor, an FPGA-type accelerator, a DSP-type accelerator, and/or another accelerator. In this example, the computer-readable media 204 also includes an operating system 226 and an application programming interface(s) 228 configured to expose the functionality and the data of the device(s) 110 (e.g., example device 200) to external devices associated with the client computing devices 106(1) through 106(N). Additionally, the computer-readable media 204 includes one or more modules such as the server module 136 and an output module 140, although the number of illustrated modules is just an example, and the number may vary higher or lower. That is, functionality described herein in association with the illustrated modules may be performed by a fewer number of modules or a larger number of modules on one device or spread across multiple devices.

As such and as described earlier, in general, the system 102 is configured to host the communication session 104 with the plurality of client computing devices 106(1) through 106(N). The system 102 includes one or more processing units 202 and a computer-readable medium 204 having encoded thereon computer-executable instructions to cause the one or more processing units 202 to receive streams 142(1) through 142(M) at the system 102 from a plurality of client computing devices 106(1) through 106(N), select streams 142 based, at least in part, on the communication session view 250 for each user, and communicate communication data 146 defining the communication session views 250 corresponding to the client computing devices 106(1) through 106(N).

The communication data instances 146(1) through 146(N) are communicated from the system 102 to the plurality of client computing devices 106(1) through 106(N). The communication session views 250(1) through 250(N) cause the plurality of client computing devices 106(1) through 106(N) to display views of the communication session 104 under user control. The computer-executable instructions also cause the one or more processing units 202 to determine that the communication session 104 is to transition to a different communication session view of the communication session 104 based on a user communicated control signal 156.

It is noted that the above description of the hosting of a communication session 104 by the system 102 implements the control of the communication session view in a server function of the device 110. In some implementations, the server function of the device 110 may combine all media portions into the communication data 146 for each client computing device 106 to configure the view to display. The information stored in the communication session view as described above may also be stored in a data store 138 of the client computing device 106. The client computing device 106 may receive a user input and translate the user input as being a view switching control signal that is not transmitted to the server. The control signal may be processed on the client computing device itself to cause the display to switch to the desired view. The client computing device 106 may change the display by re-organizing the portions of the communication data 146 received from the server according to the view selected by the user.

The ability of a user's device to send a notification 218 to other users participating in a communication session 104 is described with reference to screenshots of the display. The user's image may be analyzed to determine an emotion using pattern recognition or other suitable technology. Reference is made to FIG. 3, which illustrates an example of image data 199 that can be analyzed by the system to determine an emotion. The facial expressions can be used to identify an indication of a change in emotion.

For instance, a first user may utilize a client computing device 106(1) to communicate with a second user of another client computing device 106(2). Specifically, FIG. 3 depicts a user participating in a communication session 104. FIG. 3 depicts image data 199 from a client computing device 106(1-N). Image data 199 captured in 301(a) shows the user in a communication session 104 displaying a facial expression that is happy in nature. If during the course of the communication session 104, there was a change in the user's physical condition such that the user's facial expression changed to a sad expression as depicted in 301(b), the emotion detection module 198 can detect the emotion in image data 199 from the user, and in response match it to an emotion in the biometric data table 217 and then send a notification 218 to the other users.

Turning now to FIG. 4A, this is a diagram of a communication session 104 between a first user of client computing device 106(1) and a second user of client computing device 106(2) that illustrates an example according to an embodiment of the present invention. This communication session 104 consists of a series of messages that are sent between the client computing devices 106(1) and 106(2). As an example, the first user of client computing device 106(1) has sent a first message 402 to the second user of client computing device 106(2). A camera 404 of the client computing device 106(1) captures a view 406 of the first user during the communication session 104. Note that the camera 404 has captured the view 406 of the first user with a smiling expression which denotes a happy emotion.

Turning now to FIG. 4B, this is a diagram of a continuation of the same communication session 104 as previously described in FIG. 4A. After a series of exchanged messages, the first user has neither responded to the second user's message 408 nor message 410. Also, during this communication session 104, the first user's expression has changed from a smile to a frown as depicted in view 412. As such, the camera 404 of client computing device 106(1) has captured image data 199 of the first user's change in expression.

FIG. 4B also depicts a biometric sensor 195 which would enable a client computing device 106(1-N) to receive biometric values, including but not limited to pulse rate, body temperature, etc. The biometric sensor 195 is intended for illustration purposes only in FIG. 4B. Its location might be an internal component of a wearable computing device such as on a smart watch, or a sensor on a detachable device that connects to the client computing device 106(1-N). In any scenario, the biometric sensor 195 determines the pulse rate of the first user and is continuously operating during the communication session 104 by receiving new values of the user's pulse, for instance.

Turning now to FIG. 4C, this is a diagram illustrating a continuation of the communication session 104 of the preceding example. At this time of the communication session 104, the first user of client computing device 106(1) has not responded to the second user's messages 404 or 405. The biometric data 160, image data 199, and location data 111 are used by the TDM 166 to determine whether a serious health condition has arisen which would warrant a notification 218. In this example, the biometric sensor 195 is analyzing this biometric data 160 and determined that the first user's pulse rate has increased dramatically and is unusually high. Also, the image data 199 indicates that the first user's expression has changed from a smile to a frown. Additionally, the location data 111 may have determined that the user's motions are rapid and erratic. It should be understood that location data 111 is continuously monitored and any changes are continuously updated in the system.

As such, in this example, the TDM 166 has made a determination that the first user is experiencing a serious health condition and thus sends a notification 218 to the second user's client computing device 106(2). As illustrated in FIG. 4C, the notification 218 is an alert message which appears on the display screen 101 of the second user's client computing device 106(2). The notification 218 indicates that the first user may have a serious health condition and be in need of assistance.

In other embodiments, different notifications are used. For example, the second user can select the notification 218 in order to obtain specific information about the first user's condition, including but not limited to the specific pulse readings over a period of time, the physical location of the first user, allergy conditions, emergency contacts, blood type, etc.

This allows the second user to understand why the first user has not responded in this instance to previous messages 408 and 410. More importantly, the notification 218 could provide the second user with valuable information to assist the first user in the event of a life-threatening condition. It should be noted, as a consequence of the continuous operation of the TDM 166, if soon after the first user's biometric data 160, image data 199, and location data 111 fell below the threshold, the second user would be notified as such. A notification 218 might alert the other user that the first user's condition has returned to normal levels, for example.

Turning now to FIG. 5, this is a flowchart illustrating a routine 500 of an operation of a communication session 104 according to an embodiment of the present invention. At step 501 the system receives biometric data 160, location data 111, and image data 199. For example, the user might be using a client computing device such as a cell phone and/or a wearable device such as a smart watch equipped with GPS or other location identifying hardware and a front-facing camera. The client computing device can send information that it receives from all these sensors to the system. The biometric data could be a pulse. The location data could be a specific location where the user is located, and the image data is a picture of the user.

At step 503, the system monitors the pulse and determines the velocity of the user to determine the level of distress. For example, if the user had a wearable device, the device would take the user's pulse and send it to the system 102 and the system 102 would monitor the values it's receiving. In addition, it would receive values linked to the velocity of the user that could be sent from a position sensor or other similar device from the user's client device and sent to the system 102.

At step 505, the system analyzes one or more physical features of the user depicted in the image data, wherein an identification of the one or more physical features influences the level of distress. For example, when the system receives image data, it applies an emotion detection module and compares the images to the results that are associated with distress.

At step 507, the system will determine whether the level of distress exceeds a threshold or not. For example, if the user's pulse is too high, or walking too fast, the threshold could be exceeded. In another example, the user is having an expression of distress or moving too quickly or erratically. Different combinations are possible in different embodiments of the invention to determine if the threshold is met. If the level exceeds a threshold, the system 102 proceeds to step 509 where it communicates a notification 218 indicating the level of distress to a remote computing device. For example, the server sends a notification 218 to another client computing device that is in a communication session with the first user, whereby the second user is notified that the first user is in distress. If the level of distress does not exceed the threshold, no notification 218 is sent and the system will revert back to step 501 receiving biometric data 160, location 111 data, and image data 199.

Turning now to FIG. 6, this is a flowchart illustrating an operation of a communication session 104 according to an embodiment of the present invention. At step 601, the TDM 166 of system 600 begins. Next, at step 603, the system 600 receives biometric data 160 from the biometric sensors. Continuing to step 605, the system 600 calculates the first score of the received biometric data 160. Next, at step 607, the system 600 receives location data 111 and calculates the second score during step 609. Next, at step 611, the system 600 receives image data 199 and calculates the third score during step 613.

At step 615, the system 600 applies a formula to the first score, second score, and third score. Next, at step 617, the system 600 factors the context of the communication session 104. Next, at step 619, the system 600 determines whether a threshold has been exceeded from application of the preceding formula in step 617. If the answer is yes, the system proceeds to step 621 and sends the notification 218 to the client computing device 106(N) of the other user. On the other hand, if the threshold has not been exceeded, the system 600 reverts to step 601 at the start of the TDM 166 process continues.
